Chain Versus Ring: Characterization of a Meta‐Phenylene Ladder Polymer and Its Octameric Macrocycle

Chemistry – A European Journal, Volume 32, Issue 16, 25 April 2026.
The synthesis and comprehensive spectral and photophysical analysis of a methyl‐substituted ladder meta‐phenylene macrocycle (MeLMMP) and its polymer analogue (MeLPMP) show that, despite differing topologies (macrocycle vs. polymer), both display nearly identical electronic and photophysical properties due to cross‐conjugation.

Piezoresistive Monitoring of Carbon Nanomaterial‐Reinforced Epoxy Composites Under Cyclic and Fatigue Loading: A Review

Advanced Engineering Materials, Volume 28, Issue 8, 22 April 2026.
Carbon nanomaterial‐reinforced epoxy composites exhibit pronounced piezoresistive behavior, enabling intrinsic damage sensing under cyclic and fatigue loading. This review critically compares carbon nanotube and graphene systems, correlating filler content, percolation threshold, and gauge factor with sensing stability and damage evolution.

3D‐Printed Giant Magnetoresistive (GMR) Sensors Based on Self Compliant Springs

Advanced Engineering Materials, Volume 28, Issue 8, 22 April 2026.
This work explores 3D‐printed GMR sensors utilizing self‐compliant spring structures and conductive PLA composites. By optimizing arm width, we achieved high piezoresistive (0.34%/mm) and magnetoresistive (0.77%/mT) sensitivities. Demonstrated through Bluetooth‐integrated pressure and magnetic position sensing, these full printed low‐cost, customizable

Modeling and Design Principles for Plasmonic Nanoparticle‐Enhanced Perovskite Solar Cells: A Comprehensive Review

Solar RRL, Volume 10, Issue 7, 15 April 2026.
Perovskite solar cells have reached high power‐conversion efficiencies, yet further gains require improved optical design, particularly in the near‐infrared. This review surveys analytical and numerical studies on plasmonic nanoparticle‐enhanced perovskite solar cells (PSCs), clarifying key enhancement mechanisms. The influence of nanoparticle material,
